Abstract: Certain aspects of the present disclosure provide techniques for determining default parameters to use in the absence of a signaled uplink transmission configuration indicator (TCI) state for uplink transmissions. In some cases, a UE may determine, based on one or more rules, at least one of a default uplink beam or default path loss reference signal (PL RS) to use an uplink transmission in the absence of a signaled uplink transmission configuration indicator (TCI) state for the uplink transmission; and send the uplink transmission in accordance with the determination.

Abstract: Aspects of the present disclosure provide techniques for beam failure detection and related timing determinations, such as for applying a default beam after beam failure recovery response (BFRR) message. A method by a user equipment (UE) may include detecting failure of a beam associated with a first cell. The detecting can include performing beam failure detection (BFD) of a beam pair link (BPL) associated with the first cell (e.g., secondary cell (Scell)). The first cell can be in carrier aggregation (CA) with a second cell. The UE may send a beam failure recovery request (BFRQ) message on a second cell (e.g., a primary cell (Pcell)). The BFRQ message can include a candidate recovery beam for the first cell. The UE can receive a BFRR message on the second cell and determine a duration from reception of the BFRR message until using a default beam for communications on the first cell.

Abstract: In an aspect, a user equipment (UE) transmits, to a base station, an uplink (UL) power change capability indication. The base station receives the UL power change capability indication, and transmits, to the UE, scheduling information for one or more UL transmissions that include one or more UL power changes based on the UL power change capability indication.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform path-loss estimation to support uplink transmit power control. The UE may perform path-loss estimations on path-loss reference signals configured by a base station. In some cases, the base station may update (e.g., activate, deactivate, or both) particular path-loss reference signals using a medium access control (MAC) control element (CE). The UE may determine which path-loss reference signal or signals to use for path-loss estimation based on one or more techniques. For example, the UE may filter path-loss measurements over a time duration or may use a single, unfiltered path-loss measurement for path-loss estimation. Additionally or alternatively, the UE may receive deactivated path-loss reference signals (e.g., for a set amount of time or for any amount of time) or may refrain from receiving deactivated path-loss reference signals.

Abstract: Methods, systems, and devices for wireless communications are described. Described techniques provide for autonomous selection and updating of beams from a set of candidate beams for a slot aggregation configuration. A user equipment (UE) may receive a set of reference signals associated with the set of candidate beams for communications with a network entity. The UE may perform a beam prediction process based on measurements of the reference signals. The UE may identify, based on the beam prediction process, a subset of beams of the set of candidate beams for a slot aggregation configuration for the communications with the network entity. The UE may communicate with the network entity according to the slot aggregation configuration.

Abstract: A multi-panel (MP) user equipment (UE) (MP-UE) includes a plurality of physical antennas configurable as one of a plurality of antenna panels. The MP-UE identifies at least one of a capability and a status of each of a plurality of antenna panels of the MP-UE. The MP-UE then reports, to a base station in uplink, the identified at least one of the capability and the status of the plurality of antenna panels in accordance with an antenna panel reporting configuration for the MP-UE.

Abstract: Apparatus, methods, and computer program products for beam updating are provided. An example method includes receiving DCI. The method further includes determining, based on the DCI, whether the DCI is associated with a beam update for uplink, downlink, or a combination of the uplink and the downlink. The method further includes determining, from the DCI, a TCI state that indicates a beam for the uplink, the downlink, or the combination of the uplink and the downlink.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a tracking reference signal (TRS) pattern to be used for receiving a TRS. The TRS pattern may indicate a plurality of TRS symbols of the TRS, one or more TRS symbols of the plurality of TRS symbols having a bandwidth that is different than a bandwidth of at least one other TRS symbol of the plurality of TRS symbols, or having a discontinuous tone allocation. The UE may receive the TRS based at least in part on the TRS pattern. Numerous other aspects are provided.

Abstract: A method of wireless communication is performed by a user equipment (UE). The method receives, from a network, a configuration for a decision making module. The method also executes the decision making module to determine a selection parameter for a configuration of at least one machine learning module. The method selects the configuration of the at least one machine learning module based on the selection parameter. Further, the method reports, to the network, a decision resulting from executing the decision making module.
